Help

I am trying to find a factory intercooler. I thought it was a from a series 6 RX7 front mount? They are similar size to a GTR but a little smaller (I thought -but could be wrong...)

Anyone seen one, or know of a website showing one, or know of anyone selling something similar?

I might settle for an EVO 5 (or greater) front mount too.

If you would like to know, I am going to modify it slightly and use it for the SR20DET motor I am putting into my 1600.

Cheers

a mate used a gtr cooler but it was huge had to cut the front up
i would look at a evo cooler or evern a ford xr6 core?

Don't want a GTR cooler, cause they are too big. I only want to modify end tanks If I have to...

Evo would be good, but I would need to see what size they are before even contemplating buying one.
Hence the post. Any websites giving dimensions, or selling factory intercoolers (not aftermarket ones...)

Maybe even wreckers?

not too sure mate sorry on that one...
but have u looked at a ford cooler? i seen them go for like 50 bucks on the ford sites....
might be worth looking at them as well

Get a hybrid $300 brand new, 450x300x76 spot for a 1600

Got any photos? OR webpages which have images of this cooler?

Just had a quick scout around for series 6 mazda RX7 factory intercoolers and they are pissy little small things!! (doh!)

Must have been something else I saw!

The factory ford coolers are too small for your purposes I would think (Unless you get a typhoon one which would be unlikely since they just came out). Go the hybrid simply cause of the price, checkout turbovans thread in the members ride section which explains what he did too fit it.

im fairly sure this is an EVO cooler not sure what model, but just thought it might help.



And here a 450x300x76 hybrid (copy) in a poobird.

Just out of interest have you considered a water-to-air cooler. I know there more complicated and heaver but they save cutting up your car and the PWR ones look the business I reckon. Again, just my opinion though..

Guys,

Evo is about the size that I want. Thanks heaps for the photos datto_boy. Anyone confirm if that is an EVO intercooler, and what year?

Secondly, I can't reveal the design of the intercooler mount brackets and the like 'cause I wanna suprise you. Put it this way, it is going to be different.

The hybrid 450x300x76 is a little too big. (but close) 275 in height is about the go.

Water to air are good, but that is a whole different topic of conversation. For example, I would have to change the inlet manifold because the PWR W2A coolers won't take the swirl [out] of the air from turbo's impeller, unlike an A2A intercooler. I would have to do alot of stuffing around to fit her properly aswell...

what does this mean?

Hey im pretty sure thats a VR4 intercooler in the pic above... dunno what year tho, theres a thickness difference between genuine Evolution and VR4 ones like 70mm while the others 60mm.

Look it (Turbophile) i think its called its a datto site, theres a how to get one in guide but this involves cutting the end tank and reversing it so there both on the bottom... unless you plan on removing one of the inner headlights... LEGAL BY THE WAY cause 1600's have outter high beam too.

Um i wanna get one of those copy hybrid ones i think the 450mm size cause by the time you buy a evo cooler and get someone to aluminium weld it back up its too expensive... here the hybrid copys r less than $300. I think which ever way you go youll still have to cut your front for the pipes and to recess it far enough back so its behind the grill... im not into hanging out the front coolers

If you cut your front radiator pannel make sure you leave enough and bend the edges up like original as it retains strength in this area

Go to modyourcar.com i think theres a printable photo of the copys which has all the dimensions on it, i used this and made a template out of cardboard to suss out fitting but you have to take in account the hoses and clamps also

Stock Rx7 ones are top-mount so they need mods anyhow, other ones to check out are Pulsar GTiR or Supra ones the supra ones are cheap as piss but dont look as good as the polished ones...

(by the way, I ended up editing my post to make a little more sense... Sorry!)

Don't really know what I was smoking when I wrote that post... What i was trying to say is that the W2A intercoolers are less efficient in taking out the swirl or turbulence of the compressed air from the turbo. BUT upon reading the post again, maybe the core of a water to air intercooler would be sufficient enough to remove the swirl (turbulent air)



I guess it depends on the W2A intercooler, and how they are designed. TO me A2A intercoolers take the swirl out with the end tanks and then you have less restriction passing through the core. The PWR intercooler is just a barrel, so really the swirl of the air as it hits the core of the W2A is loosing energy. BUT then again, due to the size of the intercooler, the back pressure or pressure loss would be minimal...

Someone like to impart their knowledge and help me out on my poor explanation?

Hey SR20Datsun,

I have had a look in one of those barrel intercoolers... There are long tubes just like a normal intercooler core inside, its not just an empty barrel with a water jacket. I wouldn't consider the swirl to be a huge issue... some turbulence inside the intercooler is good - it helps each molecule of air to have a better chance of cosying up to the chilly walls and being cooled down.

Turbovan,

I've had a 'gawk' down one too. For the air to pass through the fins of any intercooler, it must be laminar flow. So any turbulence you have going into the intercooler gives back pressure. That's why the end tank design A2A intercooler is so much more efficient, because it acts as a diverging venturi, slowing the speed of the air down and at the same time, allowing it to pass through the core.
